Abstract
This research presents theoretical arguments of a new approach called Technique “K,” which aims to reduce student’s anxiety before a cognitive challenge. Through a randomized, controlled clinical trial, we evaluate the Beck Anxiety Inventory and salivary cortisol. We compared the results in the last year of high school, who were facing school tests, before and after the application of the “K” technique (intervention group) and placebo (control group). Statistical analyses consisted of using the Chi-square, Spearman and the Wilcoxon test. The principal component analysis observed in the case group, - 10.50 (-18.25; -4.75), was statistically higher than the control group, -6.00 (-8.75; -1.25). It is not possible to identify statistical significance (p = 0.462) in the variation of salivary cortisol concentration. The results suggest the effectiveness of the “K” technique in managing anxiety in high school students. Although, future research is needed to extend the preliminary data obtained in this study.
